Huawei 5770 mifi

[macliam]

I have a Huawei 5770 that I used with O2 PAYG in the UK. I have now relocated to Portugal, but the unit is locked to O2 so I can't use a local sim. How can I get the unit unlocked ("officially", I'd prefer not to use backstreet processes!)

Follow the advice here. If there is anything you aren't sure about, then give us a shout.

This seems handset related - and presumes I still have an O2 sim. Currently the Mifi unit has a GiffGaff sim in it as this uses the O2 network and is roaming to MEO in Portugal, but my GiffGaff support is due to end in 5 days time........

Therefore there is no O2 "phone number" to quote and I'm not likely to find a spare O2 sim here in Portugal!

It'll need to be a back door job then unfortunately.

That's it ,is it? "You're not paying us any more, so sod off"

Is that the official position?

It's not official, but it's the only way you'll do it without an o2 sim.
